Ground-state energy of InAs quantum dots (QDs) in the GaAs matrix can be changed significantly by introducing a thin AlAs layer (1 nm). The photoluminescence (PL) peak …
We report photoluminescence data from three InAs/AlAs quantum dot samples with different densities and separations, respectively. For medium density the quantum dot related …
We have studied photoluminescence (PL) from single InAs self-assembled quantum dots (QDs) by micro-PL measurements and, in particular, studied the excitation intensity …
The temperature dependence of the time-resolved photoluminescence (PL) of self- assembled InAs quantum dots (QDs) with InGaAs covering layers was investigated. The PL …
